【摘要】：基于3维环境的空间统计信道,提出MIMO天线阵列下的VMF分布模型.研究MIMO多天线ULA,UYA和UCA在移动台和基站的拓扑结构,得到VMF(Von Mises Fisher)分布模型下ULA,UYA和UCA的空间衰落相关性(SFC)函数的表达式,比较不同天线阵列对平均仰角(MEOA)的灵敏度.研究表明,MIMO天线阵列的SFC由集中参数、平均方位角(MAOA)及平均仰角(MEOA)决定,该模型的信道性能结果与理论一致.
[Abstract]:Based on the spatial statistical channel in 3D environment, a VMF distribution model for MIMO antenna array is proposed. The topological structure of MIMO multi-antenna ULA,UYA and UCA in mobile station and base station is studied. The expression of ULA,UYA and UCA's spatial fading correlation (SFC) function under VMF (Von Mises Fisher) distribution model is obtained, and the sensitivity of different antenna array to average elevation (MEOA) is compared. It is shown that the SFC of the antenna array is determined by the centralized parameters, the average azimuth (MAOA) and the average elevation angle (MEOA). The channel performance of the model is in agreement with the theory.
